Is there a problem with the idle control? If so, the interlock won't
help. But if the problem is and always was idiots [and others] not
operating the car correctly, the interlock reduces the problem.

Because, as we both agreed three posts ago, the engine computer isn't
the problem. The problem is people accidentally hitting the gas
instead of the brake. The first defense against this is good
ergonomic design to minimize the chance of this happening. The second
defense is the interlock which is cheaper, more quickly implemented
and more easily mandated by law, if necessary.

I think the problem was pretty much confined to AT cars.

it would be more effective to put an i.q. interlock on the ignition.

How about that the interlock is only on US cars?
